- remove unneeded vlc code < 0 check
- reorder vlc code handling so that the unlikely escape decoding
  part comes last
- move overflow check out of the decode loop
- branchless sign conversion

(max packet size should fit in 13 bits as a kB value, so 1<<23, plus the
header which is 10 bytes), and as per mpegenc.c internal assumptions
(min packet size is 20 bytes). See "[PATCH] make packet_size in
AVFormatContext unsigned" thread.

These are only supposed to be called once per row, not once per macroblock.
~1.5% faster according to oprofile.

of decoding.

~8% faster VC-1 decoding.
Possible future optimization: clear blocks after use instead of before, and for
DC-only blocks, only clear the DC coefficient.

Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).
